Description
Technical field
The utility model relates to lighting device, especially a kind of LED lamp that dispels the heat good.
Background technology
The colourity of the light that the LED lamp sends is good, human eye vision brightness height, and the LED lamp is freedom from repairs also, and the life-span is long, energy-conserving and environment-protective.
At present, at LED lamp work heating, use fin that the LED lamp is dispelled the heat, but because the heat dispersion of fin is poor, radiating efficiency is low, makes the life-span of LED lamp significantly reduce.
The light linearity that the LED lamp sends is good, and existing LED lamp can not carry out luminous intensity distribution at illumination, makes that LED lamp illumination zone is little, and versatility is low.
Summary of the invention
The utility model provides a kind of LED lamp of excellent radiation performance.
For achieving the above object, a kind of LED lamp that dispels the heat good of the utility model statement, comprise lamp body, the top of this lamp body is radiator, diffuser is installed at heat-absorbent surface edge at this radiator, LED lamp group is installed in this diffuser internal cavities, its key is: the bottom surface sections at described radiator heat-absorbent surface is installed radiating tube, this radiating tube is arranged in described diffuser internal cavities, the radiating surface of described radiating tube is close to described radiator heat-absorbent surface, installation base plate on the heat-absorbent surface of described radiating tube, described LED lamp group is installed in above the described substrate.
LED lamp group work heating, heat is delivered on the substrate, substrate continues heat is delivered on the heat-absorbent surface of radiating tube, radiating tube is delivered to the heat of heat-absorbent surface the radiating surface of radiating tube, the radiating surface of radiating tube is delivered to radiator with heat again, and the heat that LED lamp group is sent by radiator is delivered in the surrounding air.
The cross section of described radiating tube is a hexagon, the polyhedron that this radiating tube forms, wherein radiating surface is close to described radiator heat-absorbent surface, other five sides of described radiating tube are heat-absorbent surface, on five heat-absorbent surfaces of described radiating tube, a described substrate is installed all, described LED lamp group all is installed on the every substrate.
It is heat-absorbent surface that radiating tube has five sides, five sides are not at grade, installation base plate all on five heat-absorbent surfaces, LED lamp group is installed on substrate, the different direction of illumination directive that LED lamp group is sent, this radiating tube can carry out luminous intensity distribution to illumination, make illumination zone wider, be more suitable for illumination, especially road lighting makes that this LED lamp versatility is stronger.
Described radiating tube is that an inside is the metal tube of vacuum, is filled with liquid refrigerant in the internal cavities of described radiating tube, lays capillary wick on the inwall of described radiating tube.
Cavities filling liquid working medium in the radiating tube, liquid refrigerant is generally the high and evaporable liquid of specific heat capacity, the heat that thermal source produces makes near the liquid refrigerant gasification the radiating tube heat-absorbent surface, take away the heat that thermal source produces, steam cools off on the inwall of radiating tube radiating surface and discharges heat, and heat is delivered to radiator.The steam liquefy of cooling flows back to the heat-absorbent surface of radiating tube next time in the effect of capillary wick, and the liquid refrigerant that refluxes back continues to absorb heat and evaporates; So circulation constantly passes the heat that produces, and the radiating efficiency height helps prolonging service life of LED lamp.
The two ends of described radiating tube all are equipped with end cap, and this end cap bottom outward flanging forms installs journal stirrup, has installing hole on this installation journal stirrup.
, by the installing hole on the journal stirrup is installed radiating tube is fixedly mounted with screw.
Remarkable result: this LED lamp heat radiation is good, and long service life helps energy savings.The utility model both dispelled the heat to the LED lamp, can carry out luminous intensity distribution to the illumination of LED again and be more suitable for road lighting, highly versatile.
